 Security forces did not have enough time to change tactics employed with great success in November and thus lost the edge to the rebels.

Yet to recover from the spectacular attacks by the Maoists during the first phase of polling, security agencies have identified two key reasons for the setback.

Most of Thursday's attacks showed that the Maoists had far better military training and superior firepower than was estimated till now, top police and intelligence officers from various Maoist-hit states told rediff.com on Friday.

The second reason was that the Maoists had thoroughly studied the security forces and their tactics during the November 2008 assembly election in Chhattisgarh (which is widely seen as a stupendous success for the security forces) and were better prepared to be able to strike with clockwork precision and greater intensity thus inflicting devastating losses.
